The portals are believed to be guarded by higher spirits. Spirits of transcentend nature travelling across worlds like the water guardian who manifested in rock formations inmidst of roaring waterfalls. Over the centuries, as the waterfall flows over the rocks, they slowly erode, and as soon as the rock formation vanish, so does the portal, disappearing into the ether to be found at new sacred grounds, guiding seekers into the heights of lights...

Water Guardian.

Roaring waters are my home,
the place of change and new.
Every wave is there to roam,
but this know just a few.

Watching souls walk by my throne,
with faded and misty eyes.
If they just knew the soul I own,
my pliant spirit in all it lies.

Drop after drop is forming stone,
as the centuries float by.
One day I will be gone,
and then my soul shall fly.
